SmartTier lets you optimize storage tiering by matching data storage with data usage requirements. SmartTier policies relocate data based upon data usage and other predetermined requirements. Less frequently accessed data can be moved to slower disks, whereas frequently accessed data can be stored on faster disks for quicker retrieval.

FSS supports a combination of internal storage and SAN storage access to the cluster. Using SmartTier, you can map more than one volume to a single file system, and then configure policies that automatically relocate files from one volume to another to improve overall application performance. Implementing SmartTier with shared hybrid storage lets you augment overall storage with SAN storage in an online and transparent manner when local storage capacity is limited.

See the Storage Foundation Cluster File System High Availability Administrator's Guide for more information using SmartTier to maximize storage utilization and administering FSS.
